THOMAS R. ROSSITER, OF KNOVLE-BRISTOL, COUNTY OF SOMERSET, ENGLAND.

SEWING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 414,999, dated November12, 1,889. Application filed March 26, 1888. Serial No. 268,455. (Nomodel.) Patented in England November 24, 1887, No. 16,196.

T0 all whom it may concern:

Be it known that I, THoMAs ROBERT Rossl- TER, a subject of the Queen ofGreat Britain and Ireland, residing at Knowle-Bristol, county ofSomerset, England, have invented an Improved S eWing-Machine for MakingTwo Lines of Sewing Simultaneously, (for which I have obtained a patentin Great Britain, No. 16,196, dated the 24th of November, 1887,) ofwhich vthe following is a specification.

The obj ect of this invention is to provide an improved sewing-machinewhich will make two lines of sewing simultaneously and veryexpeditiously.

The invention relates to that class of machines in which the underthread is carried by a shuttle mounted so as to have a rotary motion ina horizontal plane, or a plane parallel with the cloth-plate.

According to my invention I provide beneath the cloth-plate two suchshuttles, each mounted on its carrier and carrying thread, and I mountone of them so that it can be adjusted to make the lines of sewingcloser together or farther apart, as desired. The shuttlc-carriers aredriven from the main shaft by gearing of any suitable description. Thereare two needles abovethe cloth-plate, and these needles are alsoadjustable with respect to each other, so as to be capable of beingbrought into position one over each of the shuttles.

In the accompanying drawings,Figure l is a side elevation of the forepart of a sewingmachine with the cloth-plate. and shuttleraces insection, showing the application of my invention thereto. Fig. 2 is aplan of the top side of the cloth-plate with the plates covering theshuttles removed, showing the shuttle in its carrier on one'side and theshuttlecarrier without the shuttle on the other side,

which is the case also with Fig'. 1. Fig. 3 is a plan view of the underside corresponding to Fig. 1; and Fig-1. is an inverted plan View of theneedle-bar with its needles.

A is the fore part of the goose-neck of the machine, through whichpasses the shaft for driving the needle-bar. The driving devices may beof the usual kind, the needle-bar B being fitted in the head of thisgoose-neck, as

usualbut carrying two needles, each kept in position by a screw O.

The needles b2 are received in holes b', Fig.

.4., a series of the said holes being provided, by

means of which the needles may be placed at any desired distanceapart,in accordance With the width between the two lines of stitches. In thepresser-foot l) is a slot of suicient width to allow both the needles b2to pass through. The needle-plate or part of the cloth-plate E isprovided with holes e e, and this can be removed When desired andreplaced by another having holes at a distance apart corresponding tothe distan ce apart to which the needles b2 are adjusted.

On the lower shaft for driving the shuttles are two bevel-wheels K K,each of which gears with a bevel-wheel Z, fixed on the stem of theshuttle-carrier L.

In the drawings, M is that one of the shuttles which is shown. To alterthe shuttles to correspond with the width apart of the needles, theshuttle-race N is adjustable with respect to the other by means of barsn, afixed thereto and sliding in guides in the under casting and securedin position by the screws p. lf necessary,both of the shuttles andneedles can be made adjustable; but it is only necessary that one shouldbe in practice. The bevel- Wheel which drives the adjustable shuttle iscapable of being moved longitudinally on the shaft F as the movable partof the machine is being adj usted to alter the distance between thelines of stitches by a bracket 7c, attached to the said movable partengaging a groove in the boss of the wheel K. The shuttlc-driving shaftF is driven from the shaft above or otherwise by any suitable mechanism.(Not shown in the drawings.) It may be of the ordinary description. Themachine can thus be readily altered for different widths between thelines of sewing by putting in a cloth-plate with the holes for theneedles at the required distance apart, altering the position of theneedles, and screwing up the screws O to clamp the needles in place,adjusting the shuttle-race N and fixing it by the screws p.

The parts not shown in the drawings or not used in ordinarysewing-machines.
